' To all whom it may concern.

- Be it known that 1, Roy A. F ARNAM, a

citizen of the United States, and a resident of La Grands, in the countyof Union and State of Oregon, have invented certa n new and usefulimprovements in Presses for Leveling Magnet Assemblies, .of which thefollowing is a specification. I.

My present invention relates generally to devices for facilitatingrepair workin certain instances in connection with a well known type ofautomobile in which magnets are assembled in connection with the flywheel of the motor for rotation therewith adjacent to and in; properly.spaced relation from field coils securedin connection with a stationarysupport, and itis a primaryobgect of my present invention toprovide apress adapted to receive the fly wheel and to simultaneously engage andforce the several magnets into proper position and level arrangementwith respect to the fly 'wheel, and to hold the same in such position 1while the outer screws extending through clamping plates and spacingspools are turned securely into clamping pos tion:

In this way, by accurately leveling the one face of the flywheel, theexact spacing of the field coils may be pre udged and these coilsproperly positioned before the fly wheel with its magnets is reassembledin connection with the motor, thus avoiding the present time consumingpractice of placing the fly wheel in position and removing the sameseveral times in order to obtain the proper spacing between the magnetsand the'field" coils. V

In the accompany ng drawing which il lustrates my present invention andforms apart of this specification, v 1 V w top plan view of my im-Figure 1 is proved press, Figure 2 is a side within the press,

Figure 3 is a vertical section taken dia view thereof, the fly wheel andmagnetfassembly be ng shown? Referring now to these figures, itis'conupon any work table or other suitable support, upon which thecircular base plate 10 of, a press directly rests. l his base plate hasat s aced oints de' endin ains or tenone 11 arranged to enterconformable re-v temp'lated-thatmy invention may be utilized cesses inthe table top or other support 12 i so as to thus prevent rotation ofthe base plate. The base plate has an axial opening 13 therethrough, andthrough this openin'g extends the lower reduced portion 141 off-acentral upright or press shaft lo. The

lower reduced end 14:, within the base plate 10 is keyed to the latterso as to thus lock' the shaft 15 against rotation, and said lowerreduced portion 14 is also provided with a further reduced stem 16,dependingthrough an opening of the table top or other support '12 andlocked therethrough by a nut '17 threaded upon the lower. end of thestem and abutting the lower surface ofthe table top or support 12.

The upper surface of the base plate 1( is adap-tedfor the directreception of the fly wheel 18 of that type of motor, to one surface ofwhich a fly wheel gear ring19 is connected, and tothe other sui'face'ofwhich a radial'series of magnets 20 are connected by virtue of acircumferential series of magnet holding screws 21 extending downwardlythroughclainping plates 22 and through the magnet 20 as well asthroughspacing spools 23 disposed between the magnets and the adjacent face ofthe fly wheel 18. The

heads of these screws seat in the clamping plates-or pieces 22 and thethreaded ends 2 thereof engage, the gear ring 19, and it will beobserved from a comparison of Figures 41 and -5 that the base plate 10has in additio'n to its axial opening 13, a circumferential series ofrecesses 24 therearound adjacent to its outer edge, into which thevslightly projecting threaded ends of the several magnet clamping screws21 may e'x'f tend as plainly seen in Figure 5.

r The upperportion of the upright or.

press shaft 15 is'threadedas indicated at 25 in Figure 3, and on thesethreads the clamp-,

ing wheel 26 is engaged; This wheel bears upon the press or clampingplate 27, the latter of substantially the same diameter as'the baseplate 10 and provided with a central opening by which it is mounted tomoveon the shaft 15. This clamping plate 27 has at equidistant-1y spacedpoints therearollild 2'? is in this manner so spaced with respect to thefly wheel asto evenly and uniformly engage the several magnetsflt) andevenly and unitormly hold thesaine in levelled position'with respect tothe fly wheel.

in addition to this circu erential series of spacingpins 28, the cl pingplate "27 has a circumferential series or openings suitably spacedtherearound to aline with the several magnet clamping screws 2t, theseopenings of the clamping; being indicated at 31 and being adapted forthe passage of screw drivers and like implements whereby th clampingscrews 21 may be tightly turned to their eltectiveclamping positionswhile the fly wheel and its magnet assembly are securely held within thepress.

int-a ut-Heb After the clamping screws 21 have been properly tightened,the fly wheel and its magnet assembly may then beremoved from the pressand are at this time ready for reassembly with the motor. By the use 0tthe press as proposed by my invention, the magnet assemblies may be setto one standard, and as all of the magnet clamping screws may betightened while the assembly is under pressure in the press, it is thusinsured that the magnet assembly will retain its level v after release.Under the' present practice, considerable time is wasted in bolting,removing and rebolting thefly wheel in order to get just the properspace between the magnets and the stationary field coils, and

even then, considerable inaccuracy exists unless the magnets are evenlylevelled. My

invention permits of accurate levelling jot. the ma 'n ts which resultsin amore oduceo.
